Quick Answer: When a Java program is compiled it creates a?

Java source code is compiled into bytecode when we use the javac compiler. The bytecode gets saved on the disk with the file extension . class . When the program is to be run, the bytecode is converted, using the just-in-time (JIT) compiler.

When Java program is compiling it will create?

Instead, Java programs execute on a uniform underlying virtual machine called the Java Virtual Machine (JVM). The compiler produces JVM machine code, also called JVM bytecode. to load the compiled file helloworld. class into the JVM interpreter and execute it.

Which file is created when Java application is compiled?

A Java class file is a file (with the . class filename extension) containing Java bytecode that can be executed on the Java Virtual Machine (JVM). A Java class file is usually produced by a Java compiler from Java programming language source files ( .

What is the extension of a Java program when it is compiled?

How Java programs are created compiled and run?

In Java, programs are not compiled into executable files; they are compiled into bytecode (as discussed earlier), which the JVM (Java Virtual Machine) then executes at runtime. Java source code is compiled into bytecode when we use the javac compiler. … When the bytecode is run, it needs to be converted to machine code.

How Java is compiled?

In Java, programs are not compiled into executable files; they are compiled into bytecode (as discussed earlier), which the JVM (Java Virtual Machine) then interprets / executes at runtime. Java source code is compiled into bytecode when we use the javac compiler.

What does a Java program gets compiled into Mcq?

Explanation: Java Source Code is compiled into Bytecode.

Why is Java compiled and interpreted?

Java can be considered both a compiled and an interpreted language because its source code is first compiled into a binary byte-code. … In addition, this byte-code gives Java its portability: it will run on any JVM that is correctly implemented, regardless of computer hardware or software configuration.

What is compile and run Java program?

When the Java source code is compiled dash is generated?

Question 8

What is Java Bytecode? The programs written in Java are compiled into a machine language for a virtual computer called Java Virtual Machine (JVM). The machine language for this special Java Virtual Machine is called Java Bytecode. The Bytecode files are generated with the “.

What is the use of interpreter?

As the name suggests, an interpreter transforms or interprets a high-level programming code into code that can be understood by the machine (machine code) or into an intermediate language that can be easily executed as well. The interpreter reads each statement of code and then converts or executes it directly.

What is displayed when this code is compiled and executed?

The code will compile and execute successfully showing the output Welcome to Examveda. D. The code will lead to a compilation error as the display method is not declared as abstract.

What are compiler and interpreter differentiate between them?

Interpreter translates just one statement of the program at a time into machine code. Compiler scans the entire program and translates the whole of it into machine code at once. An interpreter takes very less time to analyze the source code. However, the overall time to execute the process is much slower.
